[Mnbird] Greater or Lesser Scaup?

[Paul Lender]

Hi Folks

Here are two shots of the same bird at Como Lake, St. Paul, at about 5:40pm
tonight (1 April 2023) in bright sun.  All the other male scaup that I can
see had purplish iridescence when you could see it at all.  The angle on
the head isn't great -- sorry about that.  Without a good shot of the head
in profile, is the green iridescence definitive for Greater?

Thanks in advance...
